Application filed July 30,

l This invention relates to a seat construction for baby carriages ofthe type having: an. ad;-

justable back and the object is to provide an improved construction ofthis kind which will have various advantages as willappear 1 as thefollowing description of an illustra-- tive embodiment of theinventionproceeds.

Such description may be read in connection with the accompanyingdrawings illustrating one form of the invention and in these drawings; ia r 1 1.

Fig. 1 is a central vertical section through a childs go-cart. embodyingan exemplary form of the invention in its construction; 1

1 Fig.2 is a similar but fragmentary View on a larger scaleshowingtheback in a difa e of Fig. 2. a i a terent position of adjustment; and

Fig; 3 is a fragmentary section on Referring to the drawings, I haveshown in Fig. l a vehicle of the go-cart type ala figure.

though; my invention: may be applied a to other types of vehicle. I havetherein shown a seatembodying a frame 5 supported from i'ace of the backis substantially aligned with the rear edge of the seat,. as shown inthat I have herein shown the back as embodying a suitable quadrilateralframe '13 and a back-panel 15. The front face of this back willordinarily be upholstered, as indicated M317. v

The back may be supported in various po sitions'of angular ad ustment,two of which are illustrated in Figs. 1 and 2 respectively,

by-means of a rod 19 carried thereby and adapted to be interlocked witha suitable retaining means carried by theseat. I pre fer to passthe rodthrough the back to be enclosed thereby and herein have shown it aspassingthrough the upper and lower members of theirame 13, the centralportion of the rod being thus received between the side members of thatframe, the two ends projecting at the top and bottom respectively.

. The upper end may be provided with a suit- I able handle 21 by meansof which the rod may be manipulated. In the space defined by the linethe framea Suitable sprix ig: or similar mecha f nism may be housedwinch tends normally to 7 move the rod 19in one direction and I haveherein (see Fig.2)shown-ahelical spring embracing the rodiandinterposed; between I When the docking rodis' enclosed within y the backin this manner" the projecting ilower end is brought to avpositionflforwardrsof the; rear edge of theseat,the rear portion ofthe. seat'being suitably recessed as best seen at 29 in Fig. 3 to passthe same, and consequently torthe purpose .ofholdiagthe back. in ad- 1 iusted position the rod maybe engaged with, a a

a suitable cooperating rack-like device disposed wholly torward oi suchrear edge.

Herein the lower endof the rodisalso bent forwardly or' cranked toextend still further forwardand in beneaththe rear edge ofthe seat. Tomaintain the back the lower end of thelrod is provided with suitableengaging means, herein typified by a short cross head 31, the arms ofwhich are adapted to rest respectively in the openbottom notches of apair of-notched; plates 33 between which the rod works. Theangularposition of the back will obviouslydepend upon which one of the notchesis engaged by the cross-head and herein provision i'smade"for threepositions, the twoextreme positions being illustrated in Figs. 1 and'2respectively. A mere lifting movement of the backfrom'theposition ofFig. 2: toward the. vertical permits the crosshead 31 to passfromoneposition to the other moving over the projections between thenotches in the manner of a ratchet on its return stroke, suchprojectionsbeing shaped somewhat similarly to ratchet teeth for this purpose. Whenit is desired to lower thebaok to the position shown in Fig. 2, thehandle 21 is depressed, compressing spring23 and re-v leasing thecross-head from the notches and permitting the back to be swungrearwardly. The two notched plates 33 are preferably formed in'onepiece'and I have herein shown them as connected by azweb 35 which mayrest, as shown, against thebottom 7 of theseat andthey are also (seeFig. 3) provided with outwardly turned flanges by means of jectionableprojecting parts which are likely to catch the garments of the mother ornurse who is using the baby carriage, The catch means are disposedentirely out of the way'beneath the seat and may without objection beformed as shown with open topped notches forming toothlike projections.The greater rportion of the rod and thesprin which acts thereon arehoused within the bac r out of the Way and no parts are exposed at theexterior of the carriage which are likely tobecome rusty or dirty andtransfer such rust or dirt to the clothing. V V Having described. indetail the particular embodiment of my'invention shown in theaccompanying drawings, which construction is merely illustrative sincethe principles of the invention may obviously be embodied in widely(littering mechanical forms, what 1 claim as new and desire to secure byLetters Patent I shall express in the following claims. t i v 1. Incombination with'a seat a backpivoted thereto, the rear of said backadapted to align with the back edge of the seat,a springpressed rodpassing through the back fora wardly of the rear 7 ce thereof, said seatbeing suitably recessed; to pass the projecting rear edge thereof a back11in lowerend of the rod, and locking means for the cross-headcomprising a pair of notched plates between which the rod works securedat opposite sides of the recess and having a web connecting them acrossthe recess.

2. In combination with a seat having at the 'ecl thereto, aspring-controlled rod mounted in and passing vertically through saidback and having its upper end projecting therefrom at the to edge formanual reciprocation a ainst said spring substantially in the plane 0said back, the lowerend also projecting, and a rack-like structure onthe bottom of the seat forwardly of the rear edgethereof to cooperatewith said lower end whereby said back may be secured in adjusted angularposition relative to said seat; a i

3. In combination with a seat a back hinged thereto at the rear edgethereof comprising frame members and coverings for the i frame,-aspring-controlled rod carried and supported by said frame members at thetop and bottom of the back with the portion thereof which extendsbetween said members received between said coverings and with its endsprojecting, the upper end providin a handle for operating the rod, and arack-llke structure on the bottom of the seat forwardly HAROLD F.
